Yes, calcium chloride can be used on dirt roads to help reduce dust by attracting and holding moisture, which helps to weigh down the dirt particles. It is a common practice for controlling dust on gravel roads or unpaved surfaces.

Calcium chloride is typically mixed with water to create a solution that is sprayed onto roads for dust control. The recommended mixing ratio is usually around 38-42% calcium chloride to 60-62% water. This solution helps to prevent dust from being generated on unpaved roads.

Calcium chloride is sprinkled on dusty roads to help reduce dust by absorbing moisture from the air and binding with the dust particles, making them heavier and less likely to become airborne. This can help improve air quality and visibility for drivers on the road.
